ABSTRACT
PURPOSE: We developed and validated the German version of the Ureteral Stent Symptoms Questionnaire (USSQ) for male and female patients with indwelling ureteral stents. METHODS: The German version of the USSQ was developed following a well-established multistep process. A total of 101 patients with indwelling ureteral stents completed the German USSQ as well as the validated questionnaires International Prostate Symptom Score (IPSS) or International Consultation on Incontinence Questionnaire (ICIQ) and the Short Form Health Survey (SF-36). Patients completed questionnaires at 1 and 2-4 weeks after stent insertion and 4 weeks after stent removal. Statistical analyses were performed to assess the psychometric properties of the questionnaire. RESULTS: The German version of the USSQ showed good internal consistency (Cronbach's α = .72-.88) and test-retest reliability [intraclass correlation coefficient (ICC) = .81-.92]. Inter-domain associations within the USSQ showed substantial correlations between different USSQ domains, indicating a high conceptual relationship of the domains. Except from urinary symptoms and general quality of life, German USSQ showed good convergent validity with the corresponding validated questionnaires. All USSQ domains showed significant sensitivity to change (p ≤ .001). CONCLUSION: The new German version of the USSQ proved to be a reliable and robust instrument for the evaluation of ureteral stent-associated morbidity for both male and female patients. It is expected to be a valid outcome measure in the future stent research.

OBJECTIVE: To provide an overview of aspects of compliance by the recurrent stone-former, and to give recommendations for its improvement. About half of all stone-formers have one recurrence during their lifetime. To avoid recurrent stone formation it is necessary to use metaphylaxis, based on individual risks. However, all general and specific efforts are meaningless if patients are not willing or are incapable of following the proposed therapy in the long-term. METHODS: PubMed was searched for articles on urolithiasis, metaphylaxis, compliance and adherence, and relevant papers were reviewed. RESULTS: Compliance is a multidimensional phenomenon which is determined by the interaction of different factors, i.e. social and economic, therapy-related, patient-related, condition-related, and healthcare team and system-related factors. Subsequently there are several different interventional possibilities at the urologist's disposal to effect better compliance by the patient. CONCLUSIONS: The treatment and metaphylaxis of the recurrent stone-former present a particularly pertinent challenge. Patient compliance has an immense influence on the success of the treatment with respect to metaphylaxis, which is the decisive factor for preventing stone recurrence.
